The L * C * h color space uses the same diagram as the L * a * b * color space, but uses cylindrical coordinates. Lightness L * is the same as L * in the L * a * b * color space; Metric Chroma C * and Metric Hue Angle h are defined by the following formulas: : where a *, b *: Chromaticity coordinates in the L * a * b * color space For difference measurements, Metric Hue Angle difference is not.

Range: Defined by spectrum locus Path Length: Dep ends on saturation of sample colour. A Colour space in which values L*, a* and b* are plotted using a Cartesian coordinate system. Equal distances in the space approximately represent equal colour differences. L* represents lightness; a* represents the red/green axis; and b* represents the yellow/blue axis.

CIELAB color space top view CIELAB color space front view The CIE 1976 (L*, a*, b*) color space (CIELAB), showing only colors that fit within the sRGB gamut (and can therefore be displayed on a typical computer display). Each axis of each square ranges from −128 to 127. The CIELAB color space, also referred to as L*a*b*, is a color space defined by the International Commission on.

Facial color L*a*b* values among native Korean women. Measured L* values, which is the parameter representing lightness, were 60.66 ± 2.16 for the dark group, 63.87 ± 2.27 for the normal group (with a difference of 3.21 compared with the dark group), and 66.66 ± 2.34 for the bright group (with a difference of 2.79 compared with the normal group).

Step 3: Classify Each Pixel Using the Nearest Neighbor Rule. Each color marker now has an a* and a b* value. You can classify each pixel in the lab_fabric image by calculating the Euclidean distance between that pixel and each color marker. The smallest distance will tell you that the pixel most closely matches that color marker.

Figure 2. Looking at the L*C*h values for each apple in Figure 2, we can objectively determine that the apples don't match in color. Like the L*a*b* values, these values tell us that Apple 2 (sample) is lighter and duller in appearance than Apple 1 (standard).

The color space CIE L, a, b - where CIE means International Commission on Illumination - or simply LAB, is the basic mode used by the ICC profiles. All the color chain elements will use the common L, a, b mode to communicate with each others under the control of the color management system and with the help of the ICC profiles. 'L' is the lightness, whereas 'A' ( green / magenta ) and 'B.
